His argument is, for some reason, the REAL rankings after 3 weeks should be based upon (or at least influenced by) the perception of the strength of the rest of the season. Yes, he's really arguing that. In which case, Washington St. is a top ten team, because they play such a difficult schedule.
Never mind that right now that SOS number is full of confirmation bias. As the season goes on, and we actually have real results to use, the SOS numbers will change dramatically.
